I bought the atomiser to use as another one of my attachments. Whilst this is not technically a vaporiser - rather a combustion pen - it's more convenient than a traditional roll because you chuck some stuff in and off you go. You don't lose any product to the wind since the attachment isn't constantly burning. It's big enough for about 1 or 2 good hits. Only downside is its a nightmare to clean for me as I don't have one of the little cleaning brushes, but that's my own fault really because I lost the cleaning brushes I did have. Great product overall though.
